IPC: G01N27/416
Filed: 2000-05-19
Abstract: PROBLEM TO BE SOLVED: To improve diagnostic precision of the failure of a heater built in an oxygen concentration detection device used as a wide-area air-fuel ratio sensor in an internal combustion engine or the like. SOLUTION: An internal resistance value of the heater of the wide-area air-fuel ratio sensor is calculated at the decision time of a prescribed diagnostic condition (step 101-103), and the internal resistance value of the heater is compared with a control duty value. If the result is in an NG region out of the normal correlation as long as a prescribed time or longer, it is judged that disconnection or performance deterioration of the heater is generated, and warning such as lightening of MIL or the like is issued (step 104-107).

IPC: H03F3/68
Filed: 2000-06-02
Abstract: PROBLEM TO BE SOLVED: To solve the problem that, when an input voltage is near GND or Vcc, the operating current no more flows to the following stage in a clamped differential amplifier, resulting in a half output current, compared with that in the regular operation. SOLUTION: In the amplifier circuit, a clamp circuit at an npn differential amplifier operates to flow a current via a current mirror circuit acting as a second current source for a pnp differential amplifier in a first case, when the input voltage on an input terminal is low near GND. Or, a clamp circuit at the pnp differential amplifier works to flow a current via the current mirror circuit acting as a second current source for the npn differential amplifier in a second case, when the input voltage on the input type is high near Vcc, and in either the first or second case. Consequently, the current applied to these differential amplifiers becomes approximately twice and the current flowing to the following stage does not decrease thereby preventing the through-rate from lowering.
